n that I, ALEXANDER CONSTAN- Jr., citizen .of Great Britain, 4Porchester Terrace, London, have invented certain new and vements inAir-Gas Apparatus,

ollowing is a specification.

of my invention is to provide extinguishing the back flash any timelikely to occur with self supporting gas apparatus of ignition, andwhich is a of danger, and to carry my infl ect I construct my improved 1inguisher as follows, reference 0 the accompanying drawing 1 section andpart elevation of my app I ongated enlargement A which Iorms =1 adelivery pipe B from supply, an p burner, of a greater diameter that thitself and fit into this enlarged 'ated metal drum or other suit- I j javing the end remote from the cut off square, which blocks r of theenlargement with the 1 a space all around it, the secf the space aroundnot being area of the pipe, the action of ent being to spread the gas gethin layer instead of allowf in the solid mass it would if if ent werenot inserted, and by have found that no back flash 5 extinguisher, thereason being being suddenly spread out in is immediately cooled below Mat which self supporting d consequently any back flash extinguished theinstant the Specification of Letters Patent.

flame reaches the extinguisher. These extinguishers may be placed in anypart of an air gas system where back flash is likely to take place, thusrendering any system perfectly safe in this respect.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed I declare thatwhat I claim is 1. In a device for extinguishing the back flash in gasburning apparatus, the combination with the supply pipe having a portionintermediate its ends of greater diameter than the rest of the ipe, ofan imperforate elongated baffle mem er in said enlargement, said bafflehaving a substantially flat face directed toward the burner and being ofa diameter such that a space between its outer periphery and the innerperiphery of the enlargement results, the sectional area of said spacebeing not less than that of the supply pipe.

2. In a device for extinguishing the back fiash in gas burningapparatus, the combination with the supply pipe having a portion thereofsubstantially cone shaped and of greater diameter than the rest of thepipe, of an imperforate substantially cone shaped baflie member in saidenlargement the base of said member being substantially flat anddirected toward the point of consumption, there being a space all aboutsaid baffle, the

sectional area of which space is not less than that of the supply pipe?In testimony whereof I atfix my signature in presence of two witnesses.
